From what I understand, I ideally need a Type A single phase RCD for powering anything VFD like, however my head hurts trying to find a suitable source, and I could really do with replacing the old AC one for my workshop.
.
Anybody got any links to such an item in 40Amp form?

Something like this https://www.sibert.co.uk/collections/renewables-solar-pv-installation/products/rcds-typea (https://www.sibert.co.uk/collections/renewables-solar-pv-installation/circuit-protection?page=2)

might do.

Thanks Clive, but no 40A option (I should probably mention I need a 30mA trip version).
I have however discovered Zapp list two variants. I just need to find out what the difference is, but I think they have different overcurrent curves.

Why can't we go back to the good old days where nobody ever bothered about the odd electrocution? :barbershop_quartet_

I remember reading in another post
some VFD's have a removable link so you can disconnect the earth to the noise filter required to get the CE mark
with the link removed you don't have the earth leakage to trip the RCD
